In 1996, the UN-Habitat introduced the concept of child-friendly cities at the second United Nations Conference on Human Settlements (Habitat II) to make cities liveable for all. Since then, the Child Friendly Cities Initiative (CFCI) has been launched and is now present in almost 3,000 cities across more than 40 countries. In October 2021, the General Office of the National Development and Reform Commission, together with 22 other ministries, jointly issued the 'Guiding Opinions on Promoting the Construction of Child-Friendly Cities' as a guidance to bridge top-level policies with local practices and promote child-friendly cities for all ages. Issue 92 delves into various aspects critical to the place-making of child-friendly cities, including urban planning, children's play behaviour and education, community building, child safety and risk assessment, as well as international trends on the topic. Additionally, this issue highlights designs that prioritise safety and playability, community services that facilitate physical and mental health for children and families, and risk management strategies tailored to children.
